平台的运动造成雷达照射区内地面杂波频谱的平移和展宽，为了能有效的抑制地杂波，必须对杂波多普勒中心频率进行精确的估计，从而对平台运动效应进行有效的补偿。本文给出适用不同杂波背景下状况的杂波谱中心估计算法，并比较了这两种方法的优劣性，最后根据某机载雷达的回波数据对算法予以验证。

Translation and stretching of ground clutter spectrum in radar illuminating area are caused by movement of platform. In order to suppress ground clutter effectively, the center frequency of clutter spectrum must be esti-mated precisely so as to compensate effect of platform movement effectively. An algorithm for estimating center of clutter spectrum suitable for different clutter background is presented. Advantageous and disadvantageous of two methods are compared, and finally, the algorithm is verified according to echo data measured by an airborne radar.
